Late one evening, bombarded by ads showing people chilling instantly with mini-tower ACs, I caved. The Festberg Cooling Ace promised “bladeless German technology” and “instant cool” for under €60. For a compact, rechargeable cooler, I figured it was worth a shot, and boy, did I get more than I bargained for.
What Is the Festberg Cooling Ace?
Festberg markets it as a sleek, bladeless portable AC that cools, purifies, and humidifies all in one. The specs: rechargeable battery, USB-C power, 3 fan speeds, LED mood lights, and “German-patented evaporative tech” that lowers temperature instantly. It’s sold under several names, Outfany, Sherum, Libiyi, and with a 30-day money-back guarantee, and brand storytelling about “Martin Festberg.
Why I Tried It
My workspace heats up fast in the afternoon, and my power bill showed no mercy. Typical fans moved hot air, while real ACs were out of budget. So a portable, desk-sized cooler with battery life sounded like the ideal middle ground, especially if it lived up to its promises.
My Experience Using It
Unboxing, it looked high-end with mood lights and a matte finish. Set it on my desk, filled the tank, and hit the power. On the lowest setting, airflow was pleasant but gentle and near-silent. On “cool” mode, it upped the airflow and noise, and felt misty on the face.
But the mist didn’t stay cold for long. After about 10 minutes, the pad warmed, and it felt like a damp fan. In my ~120 ft² office, it never lowered actual room temp, but I did feel slightly fresher during one-on-one calls. Battery life lasted about 6 hours on mid speed before dieseling out.
A bigger issue: the filter pad started smelling musty if I skipped cleaning. Selling it as a purifier? Let’s just say its “air cleaning” doesn’t hold against pollen or actual contaminants.
Eventually, I realized it’s not a mini-AC, it’s a personal, humidifying fan with lights and a rechargeable battery.
Pros
- Portable, with USB-C recharge and built-in battery
- Soft airflow and quiet on low speeds
- Adds humidity and a mildly refreshing mist
- Mood-light aesthetic is pleasing for desk use
Cons
- Doesn’t truly cool the room and only mist
- Water tank requires frequent refilling and cleaning
- Loud on higher fan settings
- Marketing claims (AC, purification, German tech) are misleading
- Filter and brand seem generic and unverified
Is It a Scam?
It’s not a scam in the sense that it works as it says, but the product is heavily oversold. The brand hides behind flashy marketing, fake urgency tokens, and unverifiable origins. What they do deliver is a humidifying fan, not a cooler, purifier, or “advanced German tech.”
Does It Really Work?
Sort of, yes, for mild, face-level mist and slight comfort. No, for actual cooling, room temperature reduction, or air purification. It’s enough to feel pleasant during a hot Zoom call, but not enough to keep a room bearable in a heatwave.
Where to Buy and Price Point
Official site lists it at €59.95 (with discount bundles and timers), but the same model appears on Amazon for as low as €43–€65. There’s no Amazon backing or consistent warranty, and buyer reviews are mixed, with some warning of broken fans or empty promises.
Alternatives
- Evapolar evaCHILL
- Arctic Air Pure Chill
- Hessaire MC18V
Conclusion: Would I Recommend It?
Only if you’re after a cute, desk-side mist fan with lights and not real cooling. The Festberg Cooling Ace offers a little humidity and airflow, but it falls short of being a genuine AC or purifier. For its price, it’s a fun gadget, especially for dry climates, but don’t expect miracles. If you want something that actually lowers the temperature or provides cleaner air, consider investing in proven evaporative coolers or even a small window unit.
